Abstract

In the frame of the activities of the MERIS validation Team and Quality Working Group, a database centralising in-situ optical measurements has been set up. The long-term objectives of this dataset are to a) enable the assessment of the MERIS L2 products delivered by the ENVISAT ground segment, b) support the monitoring of these MERIS products over the lifetime of the mission by providing a complete temporal coverage of the mission, c) support vicarious calibration of the instrument and atmospheric correction. The database contains in-situ fully normalised water leaving reflectances with concurrent and comparable extractions of the MERIS L2 products (including flags and auxiliary data). The database contains data from sources such as AAOT (P.I.: Giuseppe Zibordi), BOUSSOLE (P.I.: D. Antoine) and MOBY (P.I.: Michael Ondrusek). Further data are being acquired from a broader range of PIs through an invitation to contribute to this central tool in the MERIS validation strategy. These data are currently available to the members of the MERIS Quality Working Group under the strict data access policy of their original provider, but a future aim is to create a subset for wider distribution.
